Anti-FANCI antibodies are used in the immunodetection of the protein FA complementation group I. In humans, the canonical protein has a reported length of 1328 amino acid residues and a mass of 149.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. FANCI is known to play an important role in the repair of DNA double-strand breaks by homologous recombination and in the repair of interstrand DNA cross-links (ICLs) by promoting FANCD2 monoubiquitination by FANCL and participating in recruitment to DNA repair sites. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include Fanconi anemia group I protein, Fanconi anemia complementation group I, and KIAA1794. FANCI gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of FANCI antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
